The brunette beauty shared a picture of herself at age 13 with her gal pal Nicole Richie. The pic looks like it was taken from one of those photo booths at the mall and shows the ladies in all their '90s glory.

The two both sport similarly cut hairstyles and seem to be wearing school uniforms.

But let's be honest, the highlight of the pic is Richie's braces (okay, and her expression).

"#ThrowbackThursday @nicolerichie and I being oh so cool at 13 years old," Kardashian wrote as a caption to the hilarious pic.
